To all whom it mcy'concern:

Be it known that I, VVILLIELM KLINK, a subject of the German Emperor, and resident of No. Grosse Reichenstrasse, Hamburg, Germany, have invented certainnew and useful 1m rovements in and Relating to Piano Vio us, of which the following is a specification.

The present invention relates to improvements in stringed instruments of one string. In the former instruments of this kind the efiect of the key-board, as well known, was

transmitted onto the string pneumatically Whereas in this invention the effect is derived mechanically by the aid of lovers and the like manipulated by keys from a key board while the strin is sounded by a rotatin roller or running and.

he accompanying drawing gives a repre sentation of the invention, in two forms of construction.

Fi urel shows a form of construction in whic the strin is touched by a roller having a ring of horseiair or the like on its periphery. Fig. 2 shows another form of construction with a band of horse-hair, silk or the like running over two rollers which rotate in an I by any suitable device.

arm'which keeps stretched the running band presser (c) and the string.

The invention consists in the instrument or violin (a) having only one string, being supported on a suitable stand and arranging, over its finger-board (b), a plurality of fingering-rods (c), influenced by springs and guided 1n guides which are adapted to touch the string when manipulated by the respective keys connected Wlth the bars ('f) which are 0 eratively connected with the levers (e) and (5) arranged over the said rods. Below the lovers (6) a yoke (pl) having a counter-weight (h) is pivoted. T e yoke (g) bears a pin (y) whichrests on the movable bearing arm of the roller and presses down the latter, when a key onthe key-board is moved, 'insuch a manner that, during the de ression of a key, the said yoke is lowered wit the lowering of the respective fingerin rod (0) in such a way that the rollers ('5') an (k) (Fig. 2) having a runnin band of horse-hair or the roller (5) (Fig. 1 alone havin a ring of horse-hair, touches the string of t e instrument whereby the latter is caused tosound.

3 is a section to show clearly the relation between the The size of the rollers is chosen in such a way that the hand runs free of the string. which, only when. the roller or rollers are deressed, is touched near the bridge, and the and, on the rollers, is rubbed with colophony by a device (11) arranged thereon in any suitable :mannor. (Fig. 1).

The manner of working the instrument is as follows: than the keys are manipulated from the key- -lmard, the bars (1') work the levers (e), which are arranged upon the yoke (g), transmitting a corres ending movement on the fingering rods, (cl hy. the levers (d) whereby the roller or rollers, lowered in the movement, sounds the string according to the key which is moved. /hen the key is set free, the fingering rods (0) areliited bysprings (it). In this instrument the band is' kept stretched by any suitable device. The device which works like a bow, on this instrument, can be set in motion by a treadle arrangement, and if this device is inserted or arranged in a piano, it can be driven by springs instead. I

This invention can be arranged and em played to play like or in orchestrians, zithers, an the ll 0, and also in electrically playing pianos of any construction and its inec anisin can be coupled with that of the latter.

I claim: 1

In a stringed instrument the combination of a stand, a violin. having one string ar ranged on this stand, a finger-hoard arranged on said stand, a plurality of fingering rods (0) arranged over the string and the fingerboard, springs-(a) normally raising the fingering rods, guides which guide the rods over the string, a plurality of pivoted levers (d) to operate the fingering rods respectively, a plu-' rality of levers (e) to operate the levers (d) respectively, a plurality'of bars (f) inovably connected with the levers (e), a plurality of keys movably connected with the bars (f), 9:
